摘要
在分析铁路信息共享平台建设的基础上,指出建立共享数据库是整合现有铁路信息资源的核心,是实现铁路信息化的关键技术之一。提出一个包含数据源层、共享数据库层和主题分析层的3层体系结构共享数据库设计方案,通过研究数据联邦机制、ETL数据集成机制和基于中间件的数据集成机制,给出该共享数据库的实现方法。
Based on the analysis of railway information sharing platform construction,it was pointed out that the establishment of a shared database was the core of the integration of existing information resources,and one of the key factors in the implementation of railway information.It was proposed a data source layer contains,shared database layer and the theme of the three-layer architecture of the shared database design.By studying the data federation mechanism,ETL data integration mechanisms and middleware-based data integration system,it was given the implementation of the sharing database.
